Quick Start Guide

To evaluate the AP62301Z6-7 3A Synchronous Buck Converter Breakout, follow the steps below-

Connect a power supply to the input terminals Vin and GND. Set VIN to 12V.
Connect the positive terminal of the electronic load to Vout and negative terminal to GND.
EN has a positive voltage through a 100K pull-up to Vin. No supply input is required for EN.
The evaluation board should now power up with a 5.0V output voltage.
Check for the proper output voltage of 5.0V (+-1%) at the output terminals Vout and GND. Measurement can also be done with a multimeter with the positive and negative leads between Vout and GND.
Set the load to 3A through the electronic load. Check for the stable operation of the SW signal on the oscilloscope. Measure the switching frequency.

Measurement Instructions

When measuring the output voltage ripple, maintain the shortest possible ground lengths on the oscilloscope probe. Long ground leads can erroneously inject high frequency noise into the measured ripple.
For efficiency measurements, connect an ammeter in series with the input supply to measure the input current. Connect an electronic load to the output for output current.
